Sending documents bricks secret chats

[majn]

Sending a document /photos to a secret chat will render the chat unusable. You can still send messages, but you cannot receive messages any longer. I believe that this is an issue with libtgl, as it happens both in telegram-purple and telegram-cli.

Reproduce in telegram-cli:

create_secret_chat PEER send_photo SECRET CHAT PEER /Users/matj/Desktop/photo.png

From this point on, it is only possible to receive messages, but all sending message won't be displayed for the other client any longer.

I can provide a few log files, the client that sends the photo is telegram-cli and the client that receives the photo is telegram-purple.

 telegram-cli log:

 create_secret_chat Mein_Handy
 Secret chat !_Mein_Handy updated access_hash
 Encrypted chat !_Mein_Handy is now in wait state
 Secret chat !_Mein_Handy updated status
 0 [14:57]  !_Mein_Handy Blein Festnetz updated layer to 17

!_Mein_Handy > s

!_Mein_Handy > d
0 [15:00]   !_Mein_Handy <<< d
0 [14:59]  !_Mein_Handy »»» s
0 [15:00]  !_Mein_Handy »»» b
!_Mein_Handy > f
0 [15:00]   !_Mein_Handy <<< f

This is the log on the receiving client when the messages are dropped, in this case telegram-purple, but it behaves similar on the iOS or android clients.
